1977 CJ 5: 258 inline 6 cylinder (4.2L); T18 factory installed four speed transmission; front dana 30 axle, dana 20 spicer transfer case with a dana 20 axle.(I now know that this was originally a Levi Straus Edition.)
So my clutch problems are really not that bad. The real problem is the mount on the Bell housing. It is cracked. So I need a new one. Question: Are there any other compatible bell housings out there? I hate to buy an OMIX China one from Morris 4x4. Since it is the "Ford Butterfly bolting pattern" can I swap out another Bell housing and still use the manual/mechanic clutch pedal linkage attachment. As usual, than you all in advance.
Look for any 1976 to 1979 CJ bell housing on Craig’s List or in the bone yard as they will be drilled and taped for the T-150 . All AMC I-6 and V8s use the same motor to bell housing bolt pattern and are completely interchangeable.

The 1977 through 1979 CJ bell housings will be drilled for both the Ford “butterfly” Transmission (T-150 ) and the CJ T-18 meaning that you can use either Transmission for the swap. Check out these sites:

So I finally dropped the Transmission . Bought a used bellhousing and now have some serious questions? First: my Transmission has the T-18 stamped onto the drivers side. My Transmission is a three speed though. The new bellhousing will not accept the bolting pattern from this Transmission . Something doesn't make sense here. At least to me? Looking for another used bell housing, but from what I have read these two should be inter-changeable. Why would a three speed be stamped with T-18 ? Any ideas?
Pushed it out of the garage and now it is sitting inoperable on the street

can ya post some pictures? I have both transmissions and can confirm they match up to the same bell housing. Even have a spare bellhousingin the garage.

Ok, after 24 sleepless hours spent fretting and frantically researching on the Inter-web- I think I have this figured out. My 1977 Jeep CJ5 is actually, at least originally, a Levi (Edition) Strauss Edition with a factory installed T-18 four speed Transmission . When I originally purchased this CJ the previous owner told me that he had bought two CJ's, one a 1977 and the other a 1978. Since he had pulled the body off of both and had a bunch of spare parts lying around, I took the running 77 and some parts from the other cannibalized 78. I had listened to him when he told me that this was a 77 with a T-150 three speed tranny. I never once even thought to try to get it into fourth gear, believing all the while that this was a three speed. I sold the original back bench, believing it was from the 78. It had dirty black and blue denim material with Levi (Edition) strauss buttons. The dude who bought it pointed it out, but I never thought anything of it. I incorrectly assumed that was part of the 78.
As for the bell housing, I am told that they are pretty much the same. But, that the T-18 requires a few modifications, specifically that the larger diameter hole on the passenger side needs to be drilled and tapped and that the hole just above the clutch fork opening requires a stud which bolts through and nuts on the outside of the bell housing.
So, I called Novak. They are accepting my full and complete exchange on the T-150 master re-build kit. They are sending a full and complete T-18 master rebuild kit. I have a shop lined up to do the rebuild, providing nothing else is serious wrong with the hard parts, for 220- 50. (They are also going to tap and mount the bell housing for me.)

Sure be glad to part with it if ya need it. We just need to work out the details. Send me a private message and we can see what we can work out. Although if you look in my thread you will see where the idiot previous owner put some "drain holes" in the bottom. http://www.jeep-cj.com/forums/f98/1978-cj7-christine-18156/index3.html#post151154
But either way if it can help ya out then that is fine
As for the info you need .. here is a great link... great info on the differances between the 2 transmissions. Oh..Grats on Finding 4th gear!! Word of caution though... if your T-18 came from a factory jeep there should be no need to drill or tap anything. If it was a Ford T-18 that would be differant. Swapping a CJ T-18 into a CJ

As far as bell housings go the 77, 78, & 79 CJ bell housings are drilled and tapped for both the Ford “butterfly” T-18 pattern (which is the same as the T-150 ) and the CJ T-18 . It is the CJ T-18 that requires the flattened head “stud” and modified clutch fork, not the Ford version.

Regardless, the "Ford T-18 Bell-housing" has nor will it never be "tapped out" to accept a T-18A jeep Transmission . So I re-tapped it. Ordered a "Rouged Ridge"/ "Omix Ada" replacement....It was tapped only for a T-150 . The "Ford Butterfly pattern" is of course "standard." Yet the bell-housing always requires "modifications." Just so we all know- "A standard bell-housing has to be drilled and tapped," in order to accept the T-18A Transmission . Most rebuilders forgo the "fourth bolt"- the bolt on the driver's side- and assume that the top 5/16th's bolts and the Transfer Case support will give the bell-housing what it needs.
Borred out all the bolt holes and re-tapped them to 1/2 inch. The bolt holes in the T-18 and the T-18 -A are 5/8".
If you buy a "used bell-housing," have no fear. You just need to drill and tap it. Make sure your lower driver's side bolt does not impede the clutch fork!

And still the flattened "head stud really makes no sense." Why go through all that effort. Between the top bolts and the skid/ Transfer Case mount, why would you have to worry?

Just so we are all on the same page, the "bell-housings" are not tapped to accept either the the "T-150 " or the "T-18a"....They are tapped from the factory to only accept the T-150 . The same "bell-housing" must be "drilled" and "tapped" to accept the "bolting pattern" of the T-18A. Omix ADA/ Rugged Ridge is only machined to accept the T-150 . (Truth.) The Ford T-18 (not A) requires that you tap it as well. You can use either 5/8 or 1/2 inch bolts. But, if you use 1/2 inch bolts you must re-tap the top holes as well.

PARTSMIKE recommends this approach. It makes no sense. in order to make the "wheel stud work" you have to tap the Transmission housing. Why?
The top bolts hold the "Transmission in place" and the skid plate/Transmission mount supports it."
please if I am wrong tell me!
